Subject: [PATCH 0/2] Add ilitek ili9341 panel driver
Date: Fri, 16 Jul 2021 18:20:41 +0800 [thread overview]
Message-ID: <1626430843-23823-1-git-send-email-dillon.minfei@gmail.com> (raw)
From: Dillon Min <dillon.minfei@gmail.com>
Since the st,sf-tc240t-9370-t dts binding already exist in stm32f429-disco.dts
but, the panel driver didn't get accepted from mainline. it's time to submit
patch fot it.
This driver can support two different interface by different dts bindings:
- spi+dpi, use spi to configure register, dpi for graphic data.
st,sf-tc240t-9370-t
- only spi, just like tiny/ili9341.c (actually, this part is copy from tiny)
adafruit,yx240qv29
I submited the first patch last year, you can find it at [1].
this patch has one major difference from that one, which is replace the low
level communication way, from spi_sync() to mipi_dbi_{command,
command_stackbuf}() interface, referred from Linus's patch [2].
both the two dpi/dbi interface was tested on stm32f429-disco board, if anyone
want to verify this patch, you need apply the clk patch for this board first,
you can get it from [3]
